Whether you choose a single test pattern or take multiple measurements, you
must select the appropriate file that you will use to generate the video test
signal. The file you select depends on the format you want to test and for
some patterns, refresh rate must also be considered. Suppose you want to test
a 1280x1024 resolution format. Within the appropriate folder, look for a file
that matches the format of the test you want to perform. If you want to test
Linearity, you would need to choose either full-field Staircase test pattern or
use the Matrix test pattern. Within the Staircase folder, you would look for a
file named 1280x1024 -Matrix.bmp (refresh rate is important for the Matrix
pattern).
4. Select the bitmap file that fits your requirements and open the file with a
program such as Paint Shop Pro. If you set up the DUT to drive a second
display, you can set the background of the second display to the bitmap file
rather than opening the file with a bitmap editor. This displays the bmp file
in full screen mode without any borders (applied for Single Monitor mode).
